Absolute crap. Nothing high powered about it. It is identical to the joyetech no battery passthru, which is also garbage, but at least it lasts a little longer. I was able to use this for about 3 hours, then it died. The joyetech one I had lasted about a month. The passthru's that come with an inline battery are far superior. Just as "powerful" as this piece of junk, and I've owned several of them, and they last on average 9-12 months. I could probably just replace the battery in them, but at about 10.00 apiece, I just replace them. Keep one in the car and one at home, beats the hell out of constantly changing batteries.
